Construction & Design

The TX6R calipers are crafted from high-strength aluminum alloy, offering a lightweight yet rigid structure capable of withstanding heavy braking forces. The six-piston configuration ensures even pressure distribution across the brake pads, which improves pad life and braking consistency. The GT-60 rotors are manufactured from Spec-37 alloy, known for its excellent thermal conductivity and resistance to warping under high temperatures.

The directional vane and slotted rotor design optimize airflow and facilitate debris removal, maintaining cooler operating temperatures and superior braking performance during prolonged use. This thoughtful engineering results in a brake system that excels in both durability and effectiveness.
